Interestingly, Boston Calling won't enforce this rule: http://www.bostonglobe.com/lifestyle/names/2018/01/24/going-boston-calling-jack-white-says-cellphones-allowed/2Id9jijFqCN3DtjlhizawK/story.html?s_campaign=bostonglobe%3Asocialflow%3Atwitter http://www.bostonglobe.com/lifestyle/names/2018/01/24/going-... and also - Pearl Jam has released information on their upcoming tour - the tickets themselves will be SmartPhone only (from their Fan Club site, Ten Club): Ten Club Mobile Tickets: No will call. No physical tickets. In order to distribute tickets more efficiently, Ten Club will be delivering all Ten Club tickets directly to your smart phone. Mobile ticket delivery requires an iPhone or Android smart phone. Instead of scanning a physical ticket at the gate, members will access tickets through their smartphone and scan directly from the screen of your mobile device. Step-by-step instructions on how to access your ticket on your phone will be sent to all Ten Club ticket holders via email when they are ready for mobile distribution. We plan to have this delivered to you by early July.
